The present invention relates, in general, to a biotechnological method for production of (3S,3'S) astaxanthin. In particular, the present invention relates to a peptide having a .beta.-C-4-oxygenase activity; a DNA segment coding for this peptide; an RNA segment coding for this peptide; a recombinant DNA molecule comprising a vector and the DNA segment; a host cell or organism containing the above described recombinant DNA molecule or DNA segment; and to a method of biotechnologically producing (3S,3'S) astaxanthin or a food additive containing (3S,3'S) astaxanthin, using the host.
La présente invention se rapporte, de manière générale, à un procédé de production, par biosynthèse, de (3S, 3'S) astaxanthine. Elle se rapporte en particulier à un peptide possédant une activité de .beta.-C-4-oxygénase, à un segment d'ADN codant ce peptide, à des segments d'ARN codant ce peptide, à une molécule d'ADN recombiné comprenant un vecteur et le segment d'ADN, à une cellule hôte ou à un organisme contenant la molécule d'ADN recombiné ou le segment d'ADN décrit ci-dessus, et enfin à un procédé de production, par processus biotechnologique et au moyen de l'hôte, de (3S, 3'S) astaxanthine ou d'un additif alimentaire contenant de la (3S, 3'S) astaxanthine.
